Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Puff Paste
Ingredients
Directions
Make the dough
On a clean surface, place the flour and work in a quarter of the butter with your hands until finely mixed.
Add enough water to achieve the same consistency as the remaining butter.
Knead the mixture until smooth, then roll it out to a thickness of ½ inch.
Laminate
Place the remaining butter, cut into slices, halfway on the rolled paste.
Dust lightly with flour, fold the paste over the butter, and press down with a rolling pin.
Let it rest for a few minutes, then roll it out thinner three times, resting between each roll to prevent sticking.

Shared aroma: isobutyraldehyde (malty, green).
Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms separate solid layers that create flakiness and lift as the pastry bakes.
- Flour
- Provides the structure that holds the dough together and supports the layers.
- Water
- Hydrates the flour so it forms a smooth, elastic dough.
The step that matters
Keeping the butter layers intact while rolling. If the butter softens or breaks through the dough, the layers blend together and the pastry loses its flakiness. Resting between rolls keeps the butter cold and the dough from tearing or sticking.
